I currently am running Centos 6 which only comes with Apache 2.2.15. Yeah, I know it is about time for me to upgrade... I get the following warning:
The minimum version of Apache needed to run Drupal without mod_rewrite enabled is 2.2.16. See the enabling clean URLs page for more information on mod_rewrite.
I have mod_rewrite enabled. Am I okay as is? I don't care about pretty URLs at the moment as I am just learning about Drupal, and will upgrade my OS someday soon.
